Practice Questions

[kostasim]

Hello

I have seen that for practice questions the following iat_type can be used for example: data: { iat_type: 'practice' }

In the score calculation this will not be used since the values for the calculation are filtered by the iat_type for example: jsPsych.data.get().filter({iat_type: 'bad-old'})

So the calculation is always dependent on the filter as I understood.

Just want to verify this :)

Thanks

Without seeing more of the code I don't think I can conclusively verify this, but what you've described seems accurate.

If you run jsPsych.data.get().filter({iat_type: 'bad-old'}) then you will get a DataCollection with only the trials that contain data: {iat_type: 'bad-old'}.

If you want to double check this, you could use the count() method on the resulting DataCollection to check that the correct number of trials are in the collection.

thanks for the answer. That is what I ment
